VPN over GSM network

[Barrydeane]

Hello and thank you for reading.

This is a how to question. I have a remote location with a Raspberry PI 3 camera. The RPi3 has a Gstreamer UDP video feed to my PC and or android tablet depending on the IP of the device.

There is no WIFI or other connection at the current site apart from 3G/4G coverage. Advise that I got was that I need to have a small Portable LTE router that has the capability to create a WiFi hot spot and have the RPi 3 connect to the that.

The question is how do I remotely log in to the the video stream over the GSM network?

3G isn't GSM.

Be that as it may...

No you don't need a hotspot...any type of 3G dongle that you can get to work with the rpi will do. Hotspot would also work, but you can probably get something that is cheaper if you go the dongle route. Or even connect it via ethernet. Don't think you need a VPN either unless the feed is somehow very sensitive info.

Had a similar setup a while ago. It worked, but tended to fall over a lot due to the cellular network connection "freezing". Also, I recall I could not VPN in to the remote Pi when it was the VPN server (blocked somewhere on cellular network). I eventually had a VPN server at home, with the remote Pi connecting as client.

HvRooyen.

So how did you do all of that? I need some " How to for dummies" explanation

Quick reply, on phone - will expand later if needed.
2 RPi's and a Cellular WiFi router. Searched Google for "Raspberry pi openvpn server" and "Rpi Openvpn client". Followed instructions. (not being sarcastic)
